So a good friend of mine since middle school and this girl we went to high school with dated for awhile. Probably about 3-4 yrs off and on until our freshman year in college. Their relationship was always rocky but they always got back together very quickly after breaking up. I'm not to sure of the details of the final breakup but from what I have heard through the grapevine is he started treating her like shit and dating other girls behind her back while they were still together. Fast forward to now. I've always had a thing for her and supposedly so has she so a few weeks ago she invited me down to her Sorority's Semi-Formal (she goes to Auburn and I go to Ga Tech). We both had a great time and have continued seeing each other. My buddy is pissed as shit and wont even talk to me on the phone without hanging up. Last time we spoke he told me if I "pissed him off" the next time we saw each other he was going to kick my ass. That I am definitely not worried about. I'm about 4 inches shorter and have about 40lbs on him also back in HS we both wrestled and I could toss him around like a rag doll even though he had a weight advantage on me back then. He's not much of a fighter and I have a history of being a bit rough. But I really don't want to fight him because kicking his ass would add insult to injury. How do I get him to relax and stop acting like a child about me and this girl seeing each other? I have no intention of cutting ties with the girl because we really enjoy spending time together but he was a very good friend of mine up until about a month ago. Its not like I'm just using her for sex either but we genuinally enjoy each others company. OT how do I keep the girl and get my buddy back?
